Connection methodYour printer can be connected in the following way.

Connection type Speed Maximum cable length Other factors

Gigabit Ethernet Fast; varies according tonetwork traffic

Long (100 m=328 ft) Requires extra equipment(switches)

NOTE: The speed of any network connection depends on all the components that are used in thenetwork, which can include network interface cards, hubs, routers, switches, and cables. If any one ofthese components cannot operate at high speed, you will have a low-speed connection. The speed ofyour network connection can also be affected by the total amount of traffic from other devices on thenetwork.

Connect to a networkBefore you begin, check your equipment:

● The printer should be set up and turned on.

● The Gigabit switch or router should be on and functioning correctly.

● All computers on the network should be turned on and connected to the network.

● The printer should be connected to the switch.

When the printer is connected to the network and turned on, you should see the printer's IP addressappear on the front panel (192.168.1.1 in this example). Make a note of the IP address: you can use itlater to access the Embedded Web Server.

OverviewYou can print on a wide variety of printing materials, all of which are referred to in this guide assubstrates.

Substrate tips

Choosing the correct substrate for your needs is an essential step in ensuring good print quality.

Here are some tips about substrate usage.

● Allow all substrates to adapt to room conditions, out of the packaging, for 24 hours before usingthem for printing.

● Handle film and photo substrates by the edges, or wear cotton gloves. Skin oils can be transferredto the substrate, leaving fingerprint marks.

● Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. Tomake sure that the roll stays tightly wound, consider using tape to stick the leading edge of the rollto the core just before removing the roll from the printer. You can keep the roll taped duringstorage. If the roll starts to unwind, it can become difficult to handle.

NOTE: The use of tape to stick the leading edge of the roll to the core is especially important forheavy substrates, because the inherent stiffness of the substrate can cause it to loosen and unwindfrom the core.

● Using the take-up reel gives the printer better control of the substrate.

● Print quality could be impaired if you use a substrate that is unsuitable for your image.

● Make sure that the appropriate print-quality setting is selected in the RIP.

● Whenever you load a roll, the front panel prompts you to specify the substrate family that you areloading. For good print quality, it is essential to specify this correctly. Check that the substrate

belongs to the family named on the front panel, and check also that it matches the substrate profilein the RIP.

● If the substrate family shown on the front panel does not correspond to the substrate that you haveloaded, take one of the following actions:

◦ Reload the roll into the printer and select the correct substrate family. See Unload a roll fromthe printer on page 33 and Load a roll into the printer (automatically) on page 27.

◦ At the printer's front panel, select the icon, then select View loaded substrate >Change loaded substrate.

NOTE: Substrate advance calibration is not performed when the substrate family ischanged from the front panel.

CAUTION: Removing the substrate from the printer manually without using the front panel coulddamage the printer. Do this only when necessary to clear a substrate jam.

Supported substrate families

Substrate family Description

Self-adhesive Printable PVC films with adhesive on one side and a detachable liner. There are two main vinyl typesclassified by manufacturing process and application purpose: calendered (for flat surfaces) and cast(for complex 3D curves). The film may have different finishes: white, finished, transparent, reflectiveor perforated. Perforated substrates may need manual rather than automatic printhead alignment.

Examples: HP Air Release Adhesive Gloss Cast Vinyl, Avery MPI3000 (calendered), AveryMPI1005 (cast), 3M IJ-380 (cast)

Banner Usually a polyester mesh (which provides mechanical resistance) coated with PVC. There are alsorecyclable versions to cover the same applications (green banners). Banners have a wide range ofgrammage and can be grouped into frontlit, backlit and block-out categories.

Examples: HP Durable Frontlit Scrim Banner, Ultraflex Normandy Pro, Verseidag banners

Textile Printable textile substrates are usually made of polyester or cotton yarns. Some open or light textilesubstrate types come with a removable liner to prevent the ink from passing through the substrate.Textile materials that are very stiff (such as canvases) should preferably be loaded as “Low-temp."substrate. These substrates may need manual rather than automatic printhead alignment.

Film Usually a polyester film, although there are other materials such as PVC or PC. Generally thesesubstrates are used for backlit applications. Select this family setting for substrates that resisttemperatures over 95°C (200°F), otherwise load them preferably as "Low-temp." substrate. Thesesubstrates may need manual rather than automatic printhead alignment.

Example: Intelicoat SBL-7 Polyester Backlit Film

Synthetic paper Substrates manufactured using synthetic resins, mainly extruded from polypropylene (PP). They havecharacteristics similar to those of plastic film, but their appearance and properties are similar toregular paper made from wood pulp.

Examples: Yupo FEB 250, Ilford Omnijet Dry Glossy Portable Display Film

Paper-aqueous Light paper-based (cellulose) substrates with a coating compatible with water-based inks, or offsetpaper. These substrates are not compatible with solvent inks. Weight is usually around 100 g/m².

Example: HP Heavyweight Coated Paper

Paper-solvent Paper-based (cellulose) substrates with a top-coating compatible with solvent inks. Weight is usuallybetween 120 and 200 g/m².

Examples: HP Blue Back Billboard Paper, Intelicoat GPIOF140, blue back substrates

Substrate family Description

Low-temp. (includingHP Photorealistic)

Substrates sensitive to high temperatures (PP, HDPE, PET thin films), and paper-based (cellulose)substrates with top-coating that have a high stiffness and grammage (200 g/m² or higher).

Example: HP Photorealistic Poster Paper

Mesh An open and resistant polyester mesh coated with PVC and mainly used for building wrapapplications. Some of these substrates have a removable liner to prevent the ink from passingthrough the substrate. These substrates may need manual rather than automatic printhead alignment.

Example: Ultraflex Stripmesh

Porous substratesSubstrates of limited porosity may be used with this printer, but very porous substrates could damagethe printer.

To check the porosity of your substrate, see the Maintenance and troubleshooting guide.

If you use a substrate that is too porous, or fail to clean the platen as recommended, you couldexperience a decrease in print quality that would require a service repair not covered by yourwarranty.

Load a roll onto the spindle1. Make sure that the printer wheels are locked (the brake lever is pressed down) to prevent the

printer from moving.

For instructions on how to use the take-up reel see The take-up reel on page 34.

Load a roll into the printer (manually)The manual loading process should be used in the following cases:

● The substrate is unusually thin or unusually thick.

● The substrate has ragged edges.

● The substrate tends to curl at the edges.

● The printing side of the substrate faces outwards.

In other cases, the automatic loading process is recommended: see Load a roll into the printer(automatically) on page 27.

To start this procedure, you need to have a roll loaded on the spindle. See Load a roll onto the spindleon page 23.

The normal minimum substrate width is 23 inches (584 mm). To load substrates down to a minimumwidth of 10 inches (254 mm), go to the front panel and select the icon, then select Substratehandling options > Enable narrow substrate. With this option, print quality is not guaranteed.

TIP: To load a roll of textile material see The loading accessory on page 50.

1. At the printer's front panel, select the icon, then select Substrate load > Manual load.

This step is optional: you can alternatively begin at step 2.

The front panel may prompt you to remove the edge holders from the platen, if the printer believesthey are present (it may be wrong: it has no sensor to detect them).

6. Select the type of substrate you are loading.

NOTE: You should select the name of the particular substrate that you are using in your RIPsoftware, not in the front panel.

TIP: When loading very thin substrates, always select the substrate type as Banner to minimizethe vacuum pressure applied while loading; when loading very thick substrates, always select thesubstrate type as HP Photorealistic to maximize the vacuum pressure. After loading and beforeprinting, go to the front panel and change to the correct type for the substrate you are loading:select the icon, then select View loaded substrate > Change loaded substrate.

TIP: When manually loading textile substrates that you intend to use with the take-up reel, beforeselecting the substrate type it is a good idea to press the Move substrate key on the front paneland use the front panel to advance the substrate beyond the point where it may jam in the printer.This avoids the possibility of a substrate jam at this stage and also some other substrate issues;and it enables you to skip the normal check for skew.

Load a cut sheet into the printerThe printer is designed to be used with rolls of substrate. It is possible to load cut sheets into the printer,but print quality cannot be guaranteed, and you may have some difficulty in avoiding skew.

● The sheet should be at least 1067 mm (42 in) long.

● Load the sheet by following the normal roll loading process (automatic or manual, depending onthe substrate).

● During the loading process, the printer tries to detect the winding direction of the roll by turningthe spindle in both directions. When the substrate is not attached to the spindle, the followingmessage appears.

To continue loading, select Skip check – would affect IQ.

● A cut sheet is likely to be loaded with excessive skew, and the printer may not be able to correct itautomatically. If the skew as measured by the printer exceeds 3 mm/m, you are recommended tostop loading and try again. However, if the skew is tolerable, you can consider skipping theautomatic skew correction. To do so, when prompted, choose Continue with current skew.

Unload a roll from the printer1. If you used the take-up reel during printing, unload the printed roll from the take-up reel. See

Unload a roll from the take-up reel on page 47.

2. On the printer's front panel, select the icon, then select Substrate unload > Unload roll.

3. Press the OK button on the front panel as many times as needed to rewind the substrate.

4. Lift the spindle lock lever.

If the take-upreel is not enabled and you would like to enable it, select the icon, then select Take-up reel >Enable take-up reel.

The loop-shapers

When in use, the take-up reel requires a dangling loop of substrate weighed down by a loop shaper.There are two different loop-shapers provided with the printer, to be used with different substrate types.

● The heavy loop-shaper is used with banner, textile and mesh substrates. It is attached to supportson either side of the substrate. The spindle stops should not be used with this loop-shaper.

● The light loop-shaper is used with all other substrates. It lies in the substrate loop, supported onlyby the substrate, unattached at either end. It should be the same width as the substrate; therefore,it is supplied in sections of different widths that can be fitted together. The spindle stops should beused with this loop-shaper.

There are two slightly different procedures for loading a roll onto the take-up reel, depending on whichsubstrate type and therefore which loop-shaper is used: see See Load a roll onto the take-up reel(banner/textile/mesh substrates) on page 35 and Load a roll onto the take-up reel (other substrates)on page 41.

Load a roll onto the take-up reel (banner/textile/mesh substrates)

1. On the printer's front panel, select the icon, then select Take-up reel > Enable take-upreel.

2. The front panel offers you the choice of loading the take-up reel immediately, or during printing.

If you decide to load the take-up reel during printing, familiarize yourself with the proceduralsteps. Loading the take-up reel during printing requires you to complete the procedure while theprinter is feeding and printing substrate. Loading the take-up reel during printing savesapproximately 1 m (3 ft) of substrate.

TIP: If you have already loaded the take-up reel, but the printer fails to recognize that it isloaded, you can save some time by selecting Load it during printing.

The following steps assume that you have decided to load immediately. If you decide to load later,during printing, you must complete the same operations without guidance from the front panel.

10. To remove the roll from the printer after you have unloaded the take-up reel, see Unload a rollfrom the printer on page 33.

The edge holdersThe edge holders are designed to prevent the edges of the substrate from rising while printing is inprogress. They are recommended for textile and double-sided printing (even if the front panel does notsuggest them), and are not normally necessary in other situations. When not in use, they can be storedin their case at the rear of the printer.

If you choose to use them, you should place them on the platen when prompted by the front panel (thisprompt appears when using the loading accessory). Open the window, place the edge holders, thenclose the window.

WARNING! Do not touch the printer's drying enclosure. Even after you have opened the windowlatch, which disconnects the power to the drying and curing modules, the internal surfaces could behot.

The edge holders should be placed on the platen so that they slightly overlap the left and right edges ofthe substrate. The edge holders fit into holes in the platen, and they are magnetic, which helps them tostay in place.

Slide the edge holder to the left or right with your fingers so that you can see the edge of the substratein the two square holes in the side of the edge holder.

9. Select the type of substrate you are loading.

NOTE: You should select the name of the particular substrate that you are using in your RIPsoftware, not in the front panel.

TIP: When loading very thin substrates, always select the substrate type as Banner to minimizethe vacuum pressure applied while loading; when loading very thick substrates, always select thesubstrate type as HP Photorealistic to maximize the vacuum pressure. After loading and beforeprinting, go to the front panel and change to the correct type for the substrate you are loading:select the icon, then select View loaded substrate > Change loaded substrate.

10. After passing through the printer, the loading accessory can be removed by hand.

15. The front panel recommends using the Take-Up Reel (TUR). You can choose to load the TUR now,or later during printing; or you can choose not to use it at all. See The take-up reel on page 34.

16. Complete the loading process as usual and adjust the skew if necessary.

Double-sided printingThe printer can be used to print on both sides of the substrate, in the following way.

NOTE: The print should be at least 28 cm (11 in) wide, otherwise the printer will not be able to findthe reference line when printing the second side.

Outline

1. Tell the printer that you intend to print on both sides.

2. The printer prints the content that you want to appear on the first side. After each job, the printerprints a black reference line that is used to align the matching job on the second side.

3. Cut and unload the substrate.

4. Reload the cut substrate upside down and starting at the end. The reference line marking the endof the first side should be face down and near the leading edge.

5. The printer finds the reference line, and uses it to start printing the second side in the right place.

Double-sided printing can be selected in your RIP software or at the printer's front panel. The RIP settingtakes precedence: if double-sided printing is explicitly turned on or off in the RIP software, the frontpanel setting is ignored.

NOTE: If you try to move the substrate while printing on either side, the front panel asks forconfirmation, because any such movement prevents correct alignment between the two sides.

Double-sided printing in detail

1. Load the substrate in the normal way for the substrate you are using.

2. On the printer's front panel, select the icon, then select Double-sided printing > Side A.Check that the front panel shows the printer status as Ready for side A.

Alternatively, select double-sided printing in your RIP software.

NOTE: The automatic cutter and the extra bottom margin are both disabled during double-sidedprinting.

3. Send one or more jobs to be printed on the first side. Before printing the first job, the printer mayadvance the substrate by about 0.5 m (20 in) so that the second side can be completely cured.

After each job, the printer prints a black reference line that is used to align the matching job onthe second side.

NOTE: The chance of visible misalignment between the two sides increases with the length ofthe job. For this reason, in double-sided printing you are recommended not to print any single jobthat is longer than 3 m (10 ft).

4. After printing, advance the substrate a little using the Move substrate key.

● If you plan to attach the substrate to the take-up reel before printing the second side, advancethe substrate enough to achieve this.

● If you plan to attach the substrate to the take-up reel while printing the second side, advancethe substrate about 10 cm (4 in).

5. Cut the substrate, either manually or by going to the front panel and selecting the icon, thenForm feed and cut. Before cutting, ensure that the total length of the cut substrate is more than2 m (6 ft 7 in), otherwise you may be unable to load it successfully.

NOTE: The Form feed and cut command will not work if the substrate cannot be cut by thecutter.

6. Select the icon, then select Substrate unload.

7. Reload the substrate with the first (printed) side facing up as it enters the printer, and with thereference line near the leading edge. Reload if necessary until the printer finds less than 1 mm/mskew.

TIP: Although it is not strictly necessary, you may find it quicker to use the manual loadingprocedure as an initial approximation, and then allow the printer to find the reference line moreaccurately. See Load a roll into the printer (manually) on page 30. If you use only the automaticloading procedure, the printer may take some time to find the reference line.

TIP: You are recommended to use the edge holders when printing the second side, which meansusing the manual loading procedure.

TIP: If you have deliberately not attached the substrate to a spindle, and the front panel reportsthat the substrate may be detached from the core, or that the feeding direction is not detected, youcan ignore the message and continue.

8. The front panel asks, Would you like to load substrate for printing as side B? SelectYes.

9. The printer searches for the reference line on the substrate. If it fails to find it, the front panel asksyou to move the substrate using the Up and Down keys until the reference line is aligned with thepermanent line on the platen. You may find it useful to mark where the reference line is on theother side of the substrate.

NOTE: You are recommended to use the take-up reel to wind side A automatically, to avoid the "telescopic effect" that leads to deformation of the substrate edges and printhead crashes while printing side B.

Page 60: DESIGNJET L26500 / L26100 printer series - … · Color profiles ... operator-serviceable parts inside the printer except those covered by HP's Customer ... is available from various

NOTE: If you know that the automatic search for the reference line is not working (perhapsbecause the substrate-advance sensor is dirty), you can turn it off: select the icon, then selectSubstrate handling options > Auto line detection > Off.

10. Send one or more jobs to be printed on the second side. If you send more than one job, theyshould be sent in reverse order, because printing starts at the end of the second side and worksback towards the beginning.

NOTE: The jobs printed on the second side should probably be rotated 180 degrees, and mayneed to be slightly reduced in size to compensate for the contraction of the substrate after passingonce through the printer. See also the Maintenance and troubleshooting guide.

View information about the substrateOn the printer's front panel, select the icon, then select View loaded substrate > Viewsubstrate details.

The following information appears on the front panel:

● The roll status

● The substrate family that you have selected

● The width of the substrate in millimeters (estimated by the printer)

If no substrate is loaded, the message Out of substrate appears.

Substrate length trackingThe substrate length tracking feature enables you to keep track of how much substrate you have usedand how much is remaining on the roll.

1. When the roll is first loaded onto the printer you have the option to enter the length of substrate onthe roll. The amount of substrate that is subsequently used is then tracked.

2. When the substrate is being unloaded, the front panel will display the amount remaining so thatyou can note it for future reference.

3. Next time the substrate is loaded, you can enter the remaining length, and the printer will againtrack the substrate as it is used. If the substrate was never actually unloaded, for example if therewas a substrate jam and the substrate was unloaded and the printer was turned off and on, if youselect Last known length the printer will apply the values from when the jam occurred (if thetracking feature was enabled).

The remaining length of substrate is always displayed in the Substrate area of the front panel. Thisinformation may also be displayed in your RIP.

1. The length tracking feature can be disabled or enabled from the front panel. Select the icon,then Substrate handling options > Substrate length tracking.

2. Select On or Off.

Store the substrateThe following are tips for storing substrate:

● Always keep unused rolls wrapped in the plastic wrap to prevent discoloration and dustaccumulation. Rewrap partially used rolls if they are not being used.

● Do not stack rolls.

● Allow all substrates to adapt to room conditions out of the packaging for 24 hours before printing.

● Handle film and glossy substrates by the edges or wear cotton gloves. Skin oils can be transferredto the substrate, leaving fingerprint marks.

● Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. Ifthe roll starts to unwind, it can become difficult to handle.

5 Substrate settings

Download media presetsEach supported substrate has its own characteristics. The printer changes the way it prints on eachdifferent substrate. The RIP requires a description of the requirements of each substrate. This descriptionis called the “media preset”.

The media preset contains the ICC color profile, which describes the color characteristics of thesubstrate. It also contains information about other characteristics (RIP and printer settings) andrequirements of the substrate that are not directly related to color. Media presets for your printer areinstalled in the RIP.

The RIP contains media presets for only the most commonly used substrates. If you buy a substrate forwhich your RIP has no preset, you can obtain a preset for a new substrate in the following ways:

● Try to download the media preset from the substrate manufacturer's Web site.

● If it is not there, try to download it from the RIP company's Web site.

● If it is not there, check availability using the HP Media Finder search application located athttp://www.hp.com/go/latexmediafinder/

● If you cannot find it anywhere, create a new media preset in the RIP. See Add a new substrateon page 59.

● Further information can be found at http://www.hp.com/go/L26500/solutions/

Add a new substrateThis section is provided in case you decide to make your own media preset. Normally there is no needto do this if you can find ready-made presets for all the substrates that you use.

Setting Description If too low If too high

Passes The number of passes specifieshow many times the printheadswill print over the same area ofthe substrate.

The amount of ink fired per timeunit is larger and ink has lesstime to dry on the substrate. Thismay create coalescence andbanding. The boundariesbetween passes may be morevisible. However, printing speedis relatively high.

Colors are vivid, print quality ishigh. However, printing speed isrelatively low. A lower curingtemperature is needed,otherwise the substrate may bedeformed.

Drying temp.The heat applied in the printingzone removes water and fixesthe image to the substrate.

Print-quality defects such asbanding, bleeding andcoalescence may occur.

Thermal marks may be seen onthe substrate; they may appearas vertical bands in some colors.The substrate may wrinkle on theplaten, causing vertical banding,ink smears or substrate jams.

Curing temp. Curing is needed to coalesce thelatex, creating a polymeric filmwhich acts as a protective layer,while at the same time removingthe remaining co-solvents fromthe print. Curing is vital toensure the durability of theprinted images.

The print may emerge not fullypolymerized, so that the inksmears when rubbed. The printmay appear wet, after printingor later. You may need toincrease the number of passes toachieve adequate curing.

The substrate may wrinkle underthe curing module, causingdefects such as blisters or linerdetachment. The substratewrinkles may also cause verticalbanding or ink smears at thebeginning of the following plot.

Heating airflow Airflow helps to remove theevaporated water from the printzone and thus allows moreefficient drying.

In general, use the substrate family default value.

Substrate advancecompensation

Your printer was calibrated atthe factory to ensure that itadvances the substrateaccurately when using supportedsubstrates in normalenvironmental conditions.However, you may find it usefulto adjust the substrate advancewhen printing in an unusual butstable temperature or humiditylevel, or if the substrate-advancesensor is not working.

You may see horizontal bandingor grain.

You may see horizontal bandingor grain.

Input tension Tension is applied to thesubstrate from the input spindle.It needs to be constant over thefull width of the substrate, thussubstrate load is a criticaloperation.

The substrate skews and maybecome increasingly wrinkled inthe printing zone. Also, substrateadvance may be irregular,resulting in horizontal banding.

The substrate may bepermanently deformed ordamaged. Substrate advanceproblems may appear inextreme cases.

Vacuum The vacuum applied to thesubstrate at the printing zonehelps to hold the substrate downon the print platen, keeping thedistance to the printheadsconstant.

The substrate may lift up off theplaten and touch the printheads.This can smear the printedimage, cause vertical banding,cause a substrate jam or evendamage the printheads.

For sticky substrates, frictioncould be too high and substrateadvance irregular, resulting inhorizontal banding or irregulargrainy patches.

Bidirectional Specifies whether printheadsprint in both directions, whenmoving from left to right andfrom right to left.

If Bidirectional is selected, theamount of ink fired per unit oftime is larger, and therefore printquality defects such ascoalescence and banding mayoccur, especially at the sides ofthe plot. However, printingspeed is high.

If Bidirectional is unchecked thenthe printing is unidirectional andthe speed is relatively low.

TIP: You are recommended tokeep Bidirectional selected in allcases, increasing the number ofpasses if necessary to avoidcoalescence and banding.

High ink level The maximum quantity of ink willbe laid on the substrate (theHigh ink level option availableonly when the number of passesis 10 or more). The ink quantitymay be reduced by the RIP colorprofile.

If not selected, colors may lookwashed-out.

If selected, there can be excessof ink and some problemsrelated to poor drying andcuring.

TIP: Select High ink level forbacklit and some textileapplications, or if you want highcolor saturation.

Cutter The printer's built-in cutter cancut the substrate automaticallybetween each print.

Disable the cutter in the following cases:

● You want to increase the speed of printing.

● You want to use the take-up reel.

● You want to cut the substrate manually.

● The leading edge of the substrate tends to curl and causesubstrate jams.

In some cases, the cutter is automatically disabled.

Auto tracking(OMAS)

The substrate-advance sensor(also known as the OpticalMedia Advance Sensor, OMAS)is located under the print platen;it can track the substrateadvance automatically.

Disable the sensor in the following cases:

● The substrate allows ink to pass through to the platen. Cleanthe sensor after using this substrate.

● You are instructed to do so by the front panel, because thesensor is dirty or unable to track this particular substrate.

Load the substrate and print the diagnostic plot

1. Load the substrate in the normal way, paying particular attention to the following points.

● The stop at the right-hand end of the spindle has two possible positions on the spindle.Always use the leftmost position if possible. Use the rightmost position only if the substrate rollrequires the full width of the spindle.

● Turn off the substrate-advance sensor (OMAS) in the RIP if the substrate is transparent ordark, or if the printer recommends you to do so.

● Align the printheads.

2. Open the HP diagnostic chart in the RIP. The chart is stored in your printer, at http://ip-addr/hp/device/webAccess/images/new.tif, where ip-addr is the IP address of your printer.You can also find it at http://www.hp.com/go/L26500/manuals/

3. Select a suitable number of passes for the substrate family. See Select the number of passeson page 66.

Change settings while printing

You can use the front panel to change the following settings while printing.

● To change temperature and vacuum settings while printing: select the icon, then Imagequality maintenance > Adjust printing params, and choose the setting that you want toadjust. You can use the arrow keys to adjust the curing temperature, the drying temperature or thevacuum pressure. The changes that you make take effect immediately, but they are not saved: thenext job will use the settings in the media profile as usual.

● To change substrate advance calibration while printing (in case of banding): select the icon,then Image quality maintenance > Substrate advance calib > Adjust substrateadvance. You can use the arrow keys to adjust the substrate advance. The changes that youmake take effect immediately, but they are not saved for the next job. See also the Maintenanceand troubleshooting guide.

● To enable or disable extra printhead cleaning while printing: select the icon, then Imagequality maintenance > Enable extra PH cleaning or Disable extra PH cleaning. Inthis case, the change of setting is saved for subsequent jobs.

NOTE: Extra printhead cleaning shortens the life of the printhead cleaning cartridge.

Advanced settings

Here are some more advanced settings, which you are not recommended to change, unless you haveproblems that you cannot resolve any other way.

The drying and curing temperatures used by the printer are determined by adding the offset to the basetemperature. The base temperatures shown in the table are the default values for each substrate family,but may be changed by the printer depending on the printer settings in use. You cannot change thebase temperatures yourself, but you can change the offsets. The base warm-up drying temperature isdetermined by the RIP.

Your RIP may have an option to return all settings to their default values.

Setting Description If too low If too high

Warm-up dryingtemperature

The base temperature that thesubstrate in the print zone mustreach before printing starts.

This setting is determined by the RIP. You cannot change it.

Warm-up dryingtemperature offset

This offset is added to the basewarm-up drying temperature,and the total is displayed in thefront panel while the printer ispreparing to print.

Bleeding or coalescence mayappear in the first 200-300 mmof the print.

A longer time to start printing isrequired. Vertical banding or inksmears may occur.

Warm-up curingtemperature

The base temperature that thesubstrate in the curing zone mustreach before printing starts.

This setting is determined by the printer. You cannot change it.

Warm-up curingtemperature offset

This offset is added to the basewarm-up curing temperature,and the total is displayed in thefront panel while the printer ispreparing to print.

The beginning of the print is notfully dry, or looks oily.

Substrate degradation (blisters,adhesive detachment) at thebeginning of the print.

Cool-down dryingtemperature

The base temperature at whichthe substrate can be under thedrying module without beingdamaged. At the end of a job,the substrate is not stopped untilthis temperature is reached.

This setting is determined by the printer. You cannot change it.

Cool-down dryingtemperature offset

This offset is added to the basecool-down drying temperature.

A long time is needed to finishthe print.

The substrate at the beginning ofthe next print may be damaged,because it has stopped movingunder too high a temperature.This case is uncommon.

Cool-down curingtemperature

The base temperature at whichthe substrate can be under thecuring module without beingdamaged. At the end of a job,the substrate is not stopped untilthis temperature is reached.

This setting is determined by the printer. You cannot change it.

Cool-down curingtemperature offset

This offset is added to the basecool-down curing temperature.

A long time is needed to finishthe print.

The end of the print may bedamaged if the cutter isdisabled.

Minimum dryingpower

The minimum power applied inthe drying module whileprinting, so the substrate doesnot cool too much in lightlyinked areas.

A heavily inked area that comesafter a lightly inked area willhave bleeding or coalescencedefects.

The substrate is damaged inblank or lightly inked areas ofthe print, especially with a highnumber of passes.

Check the quantity of ink on the substrate

Check that the ink quantities in your media preset are adequate. Look at the color patches in the HPdiagnostic chart and check that the patches have the correct amount of ink using the guidelines below:

1. Too much ink: There are several possible symptoms of this problem.

● The last two or three scales of the chart look the same.

● Horizontal bands.

● Coalescence, grain (can be caused by an excess of light ink).

Try reducing the amount of ink in your RIP software, then reprint the chart and check again.

You may have chosen a media preset that uses more ink than your substrate allows. Consult yourRIP documentation to make sure you’re applying the right media preset, and to find out how tolower the total ink limits of the media preset. For a quick solution, you could change to a differentmedia preset that uses less ink: for example, paper-aqueous presets use less ink than self-adhesivepresets.

Faster printingThe obvious way to increase speed is to reduce the number of print passes, although this will tend toreduce print quality. Bear in mind the following considerations.

● With fewer than 10 passes, you may see an increase in grain.

● With fewer than 8 passes, the printer is more sensitive to substrate advance problems.

● With fewer than 8 passes, you may need to reduce the ink quantity to improve print quality.

● If you want to use the high ink level option, you must use at least 10 passes.

● As you reduce the number of passes, the best curing temperature may be more difficult to find,and may be more sensitive to the ambient temperature and humidity.

Here are some other suggestions for increasing the speed of printing.

● Concatenating prints saves time, because one can be sent while another is being printed.

● Disable the cutter: select the icon, then select Substrate handling options > Enablecutter > Off. With most substrates, this saves some time at the end of the printing process.

● Increase the cool-down curing temperatures. This also saves some time at the end of the printingprocess, but may cause slight substrate deformation, depending on the substrate.

See also the Maintenance and troubleshooting guide.

Color calibrationThe purpose of color calibration is to produce consistent colors with the specific printheads, inks andsubstrate that you are using, and in your particular environmental conditions. After color calibration,you can expect to get identical prints from your printer on different occasions.

Color calibration can be launched from your RIP software; see your RIP documentation for details.

In outline, the process consists of the following steps.

1. A calibration test chart is printed.

2. The HP Embedded Spectrophotometer (or, if you prefer, a different spectrophotometer) scans andmeasures the test chart.

3. The RIP uses the measurements to calculate the necessary correction factors for consistent colorprinting on that substrate.

Color calibration with the Embedded Spectrophotometer is not recommended for the following substratetypes. It may be possible to calibrate some of these substrates by using an external color measurementdevice.

● Non-opaque substrates such as clear film, backlit substrates, and some textiles.

● Substrates with an uneven surface, such as perforated vinyl or punched-window substrates.

● Substrates that suffer deformation from drying and curing, such as paper-based substrates.

● Very elastic substrates, such as some textiles without liner.

Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched norperforated), PVC banners and some opaque, stiff textiles.

Some textiles require the take-up reel for successful printing. However, the take-up reel may fail to copewith the backward movement of the substrate between the printing and scanning phases of colorcalibration. To avoid this problem, proceed as follows.

1. Ensure that the take-up reel is enabled.

2. Advance the substrate until the loop-shaper reaches its lowest position.

3. Manually rewind the take-up reel, using the buttons on the take-up reel motor, to collect thesubstrate and raise the loop-shaper until it almost touches the take-up reel spindle.

4. Set the take-up reel's wind direction to neutral.

5. Launch color calibration from the RIP.

6. When the color calibration has finished, you can re-enable the take-up reel.

Color profilesColor calibration provides consistent colors, but consistent colors are not necessarily accurate. Forinstance, if your printer prints all colors as black, its colors may be consistent but they are not accurate.

In order to print accurate colors, it is necessary to convert the color values in your files to the colorvalues that will produce the correct colors from your printer, your inks and your substrate. A colorprofile is a description of a printer, ink and substrate combination that contains all the informationneeded for these color conversions.

These color conversions are performed by your Raster Image Processor (RIP), not by the printer. Forfurther information on the use of color profiles, see the documentation for your application software andfor your RIP.

In addition to the color profiles used for printing, you may wish to calibrate and profile your monitor(display device), so that the colors you see on the screen relate more closely to those that you see onyour prints.

Color reproduction tricksLatex inks are a new technology, and there are some important guidelines when doing colorseparations (such as when creating or modifying a new media preset within your RIP) that will help tooptimize the printer output in terms of color gamut, ink usage and print quality. These are as follows:

● To achieve the best dark colors in vinyl gloss and other substrates, use as much black and as littlecomposite (CMY) as possible when creating the ICC profile.

● Light inks should be avoided as much as possible in high-density colors such as secondaries andtertiaries (dark red, blue, green, ...).

● Light inks should be restricted to the lowest-density colors, starting the use of dark inks as early aspossible. Typically, a color of more than 50% density should not contain any light inks.

● Light inks should be used at no more than 50% of maximum quantity. An excessive amount of lightinks can create gloss artifacts in vinyl gloss substrates.

Please refer to your RIP documentation for details of how to create or modify media presets.

7 The ink system

Ink system components

Ink cartridges

The printer's six ink cartridges provide magenta, light magenta, black, yellow, light cyan and cyan inkto the printheads. Each cartridge has a capacity of 775 ml.

Ink cartridges require no maintenance or cleaning, but must be shaken before installation. High-qualityprinting results continue even when the ink levels are getting low.

CAUTION: Avoid touching pins, leads, and circuitry when handling ink cartridges because theseelements are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. SeeGlossary on page 87. Electrostatic discharges are one of the main hazards to electronics products.This type of damage can reduce the life expectancy of the device.

Printheads

The printheads deposit ink on the substrate. Each printhead is connected to two ink cartridges. Forexample, the printhead shown below draws ink from the light magenta and magenta cartridges.

The printheads are extremely durable and do not need to be replaced every time an ink cartridge isreplaced. They provide excellent results even when the ink cartridges contain a low level of ink.

To maintain optimum print quality, the printheads are automatically tested at regular intervals, andautomatically serviced when necessary. This takes a little time and can occasionally delay printing.

When a printhead eventually needs to be replaced, the front panel will display a message.

CAUTION: Avoid touching pins, leads, and circuitry when handling printheads because theseelements are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. SeeGlossary on page 87. Electrostatic discharges are one of the main hazards to electronics products.This type of damage can reduce the life expectancy of the device.

Printhead cleaning kit

The printhead cleaning kit contains the printhead cleaning cartridge, the ink funnel and the ink filter.

Printhead cleaning cartridge

The printhead cleaning cartridge cleans and maintains the printheads, and seals the printheads whenthey are not in use to prevent them from drying out.

The cartridge contains a roll of cloth, which is used to clean the printheads. You are notified when 92%of the roll has been used, after which the cartridge should continue to function for at least another 140m² (1500 ft²) of printed area. A new roll lasts for at least 1850 m² (20000 ft²) of printed area.

The printer will refuse to start a print job if it detects the end of the cleaning roll. You should thenreplace the printhead cleaning cartridge with a new one.

8 Print options

Printer statesThe printer may be in any one of the following states; some of them require waiting.

● Ready (cold): The printer is powered on but has not printed yet, and the heaters are not turnedon.

● Preparing to print: The printer is warming up the heaters and preparing the printheads toprint. This takes 1 to 8 min.

● Ready for substrate

● Ready for side A/B

● Printing

● Printing side A/B

● Curing: This takes 1.5 to 5 min.

● Finishing: The printer is cooling down and preparing for stand-by. This takes 0.5 to 5 min.

If jobs of the same print mode as the already-printed file are sent while the printer is Curing (if thecutter is not enabled) or Finishing, the printer goes to Preparing to print.

To save time between prints, concatenate jobs with the same print mode (same number of passes) andturn the cutter off to skip the Curing and Finishing states. You can also use nesting to print severaljobs in the same workflow.

Even if the cutter is on or successive jobs use different print modes, it is better to print them all togetherwithout delays to minimize the time spent in Preparing to print.

Change marginsThe printer margins determine the area between the edges of your image and the edges of thesubstrate.

The margins for a particular print job are selected in the RIP software; if the job exceeds the substratewidth, it will be clipped.

The front panel offers additional settings for the bottom margin: see Table 10-4 Margins on page 85.These settings apply only to single prints when the cutter is not in use. The bottom margin is not appliedbetween several prints sent at the same time, nor during double-sided printing.

Glossary

AirflowAir is blown through the printing zone to speed up the drying process.

Back tensionThe backwards tension applied to the substrate by the input spindle, which must be constant across the width ofthe substrate. Too much or too little tension may cause substrate deformation and print quality defects.

BidirectionalBidirectional printing means that the printheads print while moving in both directions. This increases the speed ofprinting.

BleedingA print-quality defect that occurs when the ink spreads on the substrate across areas of different colors.

CoalescenceA print-quality defect that occurs when the ink spreads on the substrate within an area of the same color.

CockleA substrate condition in which it is not lying perfectly flat, but rises and falls slightly in shallow waves.

Color accuracyThe ability to print colors that match the original image as closely as possible, given the fact that all devices havea limited color gamut and might not be able to match certain colors precisely.

Color consistencyThe ability to print the same colors in a particular print job, from print to print and from printer to printer.

CuringThe substrate is heated in the curing zone to coalesce the latex, creating a polymeric film which acts as aprotective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensurethe durability of the printed images. Too high or too low a curing temperature may cause print quality defects.

CutterA printer component that slides back and forth across the platen to cut the substrate.

DryingThe substrate is heated in the printing zone to dry the ink and fix the image to the substrate. Too high or too low adrying temperature may cause print quality defects.

Edge holderA metal piece designed to prevent the edge of the substrate from rising while printing is in progress.

FirmwareSoftware that controls your printer's functionality and is stored semi-permanently in the printer (it can be updated).

GamutThe range of colors and density values reproducible on an output device, such as a printer or monitor.

HDPEHigh Density Polyethylene.

I/OInput/Output: this term describes the passing of data between one device and another.

ICCThe International Color Consortium, a group of companies that have agreed on a common standard for colorprofiles.

Ink densityThe relative amount of ink that is deposited on the substrate per unit of area.

IP addressA unique identifier that identifies a particular node on a TCP/IP network. It consists of four integers separated bydots.

LEDLight-Emitting Diode: a semiconductor device that emits light when electrically stimulated.

Loading accessoryA flexible plastic accessory that fits over the leading edge of the substrate while it is being loaded into the printer.Some substrates are difficult to load without this accessory.

Loop-shaperA cylindrical weight inserted into the loop of substrate required by the take-up reel. A light and a heavy loop-shaper are provided, to suit different substrate types.

Minimum drying powerThe minimum heat applied in the printing zone so that the substrate does not cool too much in lightly-inked areas.Low minimum power may cause print quality defects; high minimum power may damage the substrate, especiallywith a high number of passes and in blank or lightly-inked areas.

NozzleOne of many tiny holes in a printhead through which ink is deposited onto the substrate.

OMASThe Optical Media Advance Sensor, otherwise known as the substrate-advance sensor. The sensor located in theprint platen that tracks the substrate movement and increases its accuracy.

PassesThe number of print passes specifies how many times the printheads will print on the same area of substrate. Ahigher number of passes tends to improve print quality and printhead health, but reduces the speed of printing.

PCPolycarbonate.

PEPolyethylene.

PETPolyethylene Terephthalate (polyester).

PLAPolylactic Acid.

PlatenThe flat surface within the printer over which the substrate passes while it is being printed on.

PPPolypropylene.

PrintheadA removable printer component that takes ink of one or more colors from the corresponding ink cartridge(s) anddeposits it on the substrate, through a cluster of nozzles.

PVCPolyvinyl Chloride.

SpindleA rod that supports a roll of substrate while it is being used for printing.

SubstrateA thin, flat material designed to be printed on, made of paper or other materials.

Substrate advance compensationA slight adjustment to the amount of substrate advance between print passes, to compensate for the characteristicsof different substrate types. The printer normally performs this adjustment automatically, but may need to berecalibrated for substrates not supported by HP, or for an unusual ambient temperature or humidity. Incorrectsubstrate advance compensation may cause banding with fewer than 8 passes, or graininess with 8 passes ormore.

Substrate-advance sensorThe sensor located in the print platen that tracks the substrate movement and increases its accuracy. Otherwiseknown as OMAS (Optical Media Advance Sensor).

UnidirectionalUnidirectional printing means that the printheads print only while moving in one direction. The speed of printing islower than in bidirectional. In general, print bidirectional and increasing the number of passes is a better way ofimproving print quality.

Vacuum pressureThe substrate is held flat against the platen by vacuum suction. Too much or too little suction may cause printquality defects. Too little suction may also cause a substrate jam or damage the printheads.
